hi,
I’m trying to update my expo client to version 34.0.0 and I saw that i’m supposed to run again npm install -g expo-cli. However, I’m getting an error:

I have tried using administrator mode with no success.
Any ideas?
Thank you!!

Have you got any other programs open that were using it? It does say towards the end of the output that the operation was rejected by your operating system. Worth rebooting (to make sure all the locks are gone) and trying again?

Otherwise run the cmd window in Administrator mode?

nothing was opened and I ran it in administrator mode. It was solved by running yarn install expo-cli.

Thank you for your help!
